Airworthiness Directives; McDonnell Douglas Model DC-10-30 Series 
Airplanes Modified by Supplemental Type Certificate SA8452SW

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all McDonnell Douglas Model DC-10-30 series airplanes 
modified by supplemental type certificate SA8452SW, that requires 
modification of the in-flight entertainment (IFE) system and revision 
of the Airplane Flight Manual and the Inflight Manual. This action is 
necessary to ensure that the airplane crew is able to remove electrical 
power from the IFE system when necessary and is advised of appropriate 
procedures for such action. Inability to remove power from the IFE 
system during a non-normal or emergency situation could result in 
inability to control smoke or fumes in the airplane flight deck or 
cabin. This action is intended to address the identified unsafe 
condition.

DATES: Effective September 21, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 21, 2001.

ADDRESSES: The service information referenced in this AD may be 
obtained from Continental Airlines, Inc., 600 Jefferson Street HQJAV, 
Houston, Texas 77002. This information may be examined at the Federal 
Aviation Administration (FAA), Transport Airplane Directorate, Rules 
Docket, 1601 Lind Avenue, SW., Renton, Washington; at the FAA, Fort 
Worth Airplane Certification Office, 2601 Meacham Blvd., Fort Worth, 
Texas; or at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all McDonnell Douglas Model DC-10-
30 series airplanes modified by supplemental type certificate (STC) 
SA8452SW was published in the Federal Register on March 2, 2001 (66 FR 
13207). That action proposed to require modification of the in-flight 
entertainment (IFE) system and revision of the Airplane Flight Manual 
and the Inflight Manual.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

Withdraw the Proposed AD

    One commenter states that the proposed AD is not necessary because 
the subject IFE system was installed by an approved STC. The commenter 
acknowledges that there is not a single switch that can remove power 
from all components of the system, but notes that power may be removed 
from the separate components of the IFE system (e.g., components that 
supply audio broadcasts, video broadcasts, or boarding music). This is 
accomplished by pulling appropriate circuit breakers or using dedicated 
power switches for each separate component of the IFE system.
    The FAA infers that the commenter is requesting that we withdraw 
the proposed rule. We do not concur. We have determined that it is 
necessary to require a modification of the IFE system to install a 
master power switch and relay to enable the cabin crew to remove power 
from the entire IFE system with a single action. This will allow the 
airplane crew to quickly identify and isolate smoke or fumes that may 
be caused by the components or wiring of the IFE system. Further, we 
have determined that it is necessary to revise applicable manuals to 
inform the flight and cabin crews how to remove power from the IFE 
system in a single action, to aid them in determining whether or not 
the IFE system is the source of smoke or fumes. We also note that we do 
not certify circuit breakers to be used as switches on transport 
category airplanes. The use of circuit breakers as switches may result 
in degradation of the circuit breakers to the point where they will not 
trip at their rated current, thus creating a potentially unsafe 
condition by not protecting the wiring of associated systems. No change 
to the final rule is necessary.

Compliance Times for Future ADs

    One commenter states that it has no comments specific to the 
proposed actions. However, the commenter states that, if the FAA issues 
further rulemaking that applies to other IFE systems installed on other 
airplane models by STC, we should start the 18-month compliance time 
only after the following events have occurred:
    <bullet> The FAA has approved an engineering data package generated 
by the STC holder.
    <bullet> The STC holder has made modification kits available.
    We acknowledge the commenter's concern with the compliance time for 
further rulemaking actions. As we stated in the proposed AD, in 
developing an appropriate compliance time for this and similar actions 
on IFE systems installed by STC, we considered not only the degree of 
urgency associated with addressing the subject unsafe condition, but 
the amount of time necessary to accomplish the proposed actions, the 
availability of necessary parts, and the practical aspect of 
accomplishing the proposed actions within an interval of time that 
parallels normal scheduled maintenance for the affected operators. If 
we issue further rulemaking on other IFE systems installed on other 
airplane models, we will again consider these factors, as well as any 
others that are relevant.

Conclusion

    After careful review of the available data, including the comments 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule as proposed.

Cost Impact

    There are approximately 31 Model DC-10-30 series airplanes of the 
affected design in the worldwide fleet. The FAA estimates that 31 
airplanes of U.S. registry will be affected by this AD.
    It will take approximately 16 work hours per airplane to accomplish 
the required modification, at an average labor rate of $60 per work 
hour. Required parts will cost approximately $2,000 per airplane. Based 
on these figures, the cost impact of this modification on the affected 
U.S. operator is estimated to be $91,760, or $2,960 per airplane.
    It will take approximately 1 work hour per airplane to accomplish 
the required manual revisions, at an average labor rate of $60 per work 
hour. Based on these figures, the cost impact of these manual revisions 
on the affected U.S. operator is estimated to be $1,860, or $60 per 
airplane.

[[Page 43075]]

    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the requirements of this 
AD action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein will not have a substantial direct 
effect on the States, on the relationship between the national 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a 
significant economic impact, positive or negative, on a substantial 
number of small entities under the criteria of the Regulatory 
Flexibility Act. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption
